Ace flashed a smile at Samuel as he ran past, then the smile dropped as quickly as it had come. He looked up at the three with a look that was smooth and emotionless as granite. He looked down at the hand, but gingerly took the handshake anyways. "Doctor Kingslee," he introduced himself, obviously avoiding using his first name. The doctor part was hard to believe due to the ginger appearing so young. 
Z grinned at the young man with the look that Brand or Lukas may recognize as her "I'm going to make him mine" look. She had a particular fondness for ginger, which may be noticed by the many times she's attempted to flirt with Brand. But, of course, she flirted almost everyone.
